SIGNAL-LIGHT FOR RAILWAY SIGNALING, 860.

T 0 all whom it may concern.-

Beit known that I, SAMUEL H. HARRING- TON, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Signal-Lights for Railway Signaling, &c., of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to signal lights.

One of the objects thereof is to provide a construction wherein a signal glass may be so positioned as to perform its functions with a maximum of efficiency and yet the source of light be located in a convenient and safe position.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be hereinafter described and the scope of which will be indicated in the following claims.

In the accompanying drawings which illustrate one of various possible embodiments vofmy invention, Figure 1 is an elevation, shown largely in section along the line x-x of Fig. 2 in order to disclose the structure more clearly. Fig. 2 is a side elevation of the same.

Similar reference characters refer to similar parts throughout the several views.

This invention proposes, in so far as one of its features is concerned, the location of a signal glass on the upper portion of a signal supporting member or post having a source of light at the lower portion, and the provision of means whereby the radiation from said source of light may be directed. through said signal glass.

Referring now to Fig. 2, A represents a poster a lower portion, preferably provided with a supporting column B which is adapted to be buried to any desired depth in the ground. By the expression lower portion as used in this description and in the following claims is meant that portion which is within the reach of an ordinary person without artificial means of elevation.

Upon post A is mounted a column C which, in this embodiment, is formed of spiral strips Specification of Letters Patent.

of metal riveted together as shown in the drmving and crowned by a cap D. A shaft 1 is j ournaled within bearings 2 in the upper portion of the post. By the expression upper portion as used in this description and the following claims is meant that portion which is at such an elevation as is adapted for the efficient mounting of signals. Upon shaft 1 are fixed arms 3 and 4, adapted, upon the signal being set in a position indistantially parallel to the axis of the post and upon opposite sides thereof. Upon shaft 1 is also mounted a signal which, in this embodiment, is shown as a semaphore arm E and counterweight F and is operated by any desired means, not shown as it forms no part of the present invention. The word signal as used throughout this specification and the following claims is used in a broad sense as denoting any means the condition of which is adapted to indicate a given state of facts.

The ends of arms 3 and 4 are circular in form and serve as frames for glasses 5. The glass in arm 3 is adapted when the signal is in danger position to register with an opening 6 in the side of the post which is covered by a signal .grass 7. These glasses may be colored in any desired way, preferably so as to emit by their joint action a red light to indicate danger and to give forth a green or white light when the signal is in. safety position. This is accom plished in the above embodiment by having at 7 a white glass and at 5 a red glass. Obviously, if desired, another arm may be fixed to shaft 1 bearing a green glass and si nal is in safety position and vary the edlor of the light emitted thereby. By the word emit as used throughout the following claims is meant to radiate beyond the confines of the signal post. bviously, this will be chiefly through si nal glass 7.

Arm 4 is provided with a g ass in a simi lar manner and is adapted to co-act with an opening 8, preferably diametrically opposite opening 6. This opening, together with the glass S which covers the same, form what may be termed a back light and that expression is used herein to denote an auxiliary light the rays of which are l directed in a direction different from that eating danger, to assume a position subadapted to register with opening 6 when the in which the majority or" the rays of the main signal light travel.

Within the post A is mounted, by any suitable means oi support, a source of light 9. This is shown as an oil lamp, but may obviously be of any other type. The light 9 is so placed w th respect to a vertically mounted reflector 10 that its rays will be radiated from a point substantially at the focus thereof. This will result in a vertical reflection and if, as is preferably the case, a parabolic reflector is used, the rays will be reflected in substantia ly parallel lines. Opposite opening 6 and at an angle of substantially 45 with the a is ol the post is a mirror 11. Thismirror is adapted to throw the majority of the light through signal glass 7. The lower portion of the mirror, however, is cut away and a suitable inclosing member 12 conducts a portion of the light through the back light. The member 13 may be silver-ed, if desired, to economize the light and direct the same through the opening 8. A door if is prelerably located in the lower portion A through which lamp 9 may easily be reached.

The operation of the above embodiment of my invention should be largely obvious.

The majority of the light from a source of tions light placed in the position indicated in Fig. 1 is directed by the inclined mirror 11 and member 12 through the openings 6 and 8 respectively. Under normal safety condition this light is allowed to pass freely j and serves to indicate the track conditions. When it is desired to place the signal in danger condition, however, the shaft is rotated until the glasses carried by arms 3 and 4: register with openings 6 and 8 and the light is transmitted through the same and the color thereof changed.

It will thusbe obvious that I have provided a signal device whereby the light is economically used and is emitted at a point at which its action is most eflicient and yet the source of light is within reach whereby it may conveniently receive any necessary care and attention. It will also be seen that the several parts si male and durable and are adapted to perform efliciently the functions for which they are designed. Moreover, the location of the source of light protects it under all weather condiand hence renders its action more reliable. Also, the construction of the signal post combines lightness with stillness and strength.

.As many changes could be 'made in the above construction and many apparently different embodiments of my invention could be made without departing from the scope thereof, I intend that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limitin sense.

I desire it also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.
